S&P 500 Sector Weightings (2024)

Current sector weights in the S&P 500:
  1. Technology: ~28% (largest sector)
  2. Financials: ~13%
  3. Healthcare: ~13%
  4. Consumer Discretionary: ~10%
  5. Communication Services: ~9%
  6. Industrials: ~8%
  7. Consumer Staples: ~6%
  8. Energy: ~4%
  9. Utilities: ~2%
  10. Real Estate: ~2%
  11. Materials: ~2%
Why this matters:
  • If you own SPY (S&P 500 ETF), you’re already 28% tech
  • This creates concentration risk (1 sector = 1/4 of your portfolio)
  • Understanding sector weights helps you diversify better

Why Sector Diversification Matters

Risk #1: Sector-Specific Crashes

Historical sector crashes: 2000-2002 (Tech Crash):
  • Technology sector: -78%
  • S&P 500 overall: -49%
  • If you were 100% tech: Devastating
  • If you were diversified: Painful but survivable
2008-2009 (Financial Crisis):
  • Financials sector: -83%
  • S&P 500 overall: -57%
  • Banks and insurance crushed
  • Healthcare and Consumer Staples held up better
2020 (COVID Crash + Recovery):
  • Energy sector: -37% (for full year)
  • Airlines/Travel: -50% to -70%
  • Tech sector: +43% (for full year)
  • Massive sector divergence
The Lesson: If you’re overweight in the wrong sector during a crisis, you suffer disproportionately.

Risk #2: Concentration in Declining Sectors

Secular decline examples: 2010s - Traditional Retail:
  • Department stores (Macy’s, JCPenney, Sears): -70% to -99%
  • E-commerce (Amazon) grew exponentially
  • Retail sector lagged entire decade
2010s - Energy:
  • Oil/gas stocks: Flat to negative returns for decade
  • Renewable energy: Triple-digit returns
  • Energy was worst-performing sector (2010-2020)
The Lesson: Some sectors can underperform for decades due to structural changes.

Risk #3: Missing Growth in Other Sectors

Opportunity cost example: Portfolio A (Over-concentrated in Financials):
  • 2010-2020 return: ~12% annually
  • Missed tech boom
Portfolio B (Balanced across sectors):
  • 2010-2020 return: ~14% annually
  • Participated in tech + healthcare growth
Portfolio C (Overweight Tech + Healthcare):
  • 2010-2020 return: ~18% annually
  • Captured highest-growth sectors
Difference over 10 years on $100,000:
  • Portfolio A: $311,000
  • Portfolio B: $371,000
  • Portfolio C: $526,000
The Lesson: Sector allocation can be worth +6% annually (215kdifferenceon215k difference on 100k).

Help me position my portfolio for the current environment.

Building Your Sector Allocation

Approach #1: Market-Weight Allocation (Simplest)

Strategy: Match the S&P 500 sector weights Allocation (based on current S&P 500):
  • 28% Technology
  • 13% Financials
  • 13% Healthcare
  • 10% Consumer Discretionary
  • 9% Communication Services
  • 8% Industrials
  • 6% Consumer Staples
  • 4% Energy
  • 2% Utilities
  • 2% Real Estate
  • 2% Materials
How to implement:
  • Buy SPY or VOO (instant market-weight allocation)
  • Or build your own using sector ETFs (see below)
Pros:
  • Simple, proven allocation
  • Matches market performance
  • No need to predict which sectors will outperform
Cons:
  • High concentration in tech (28%)
  • May underweight sectors you prefer
  • No customization for your goals
Best for: Beginners who want to match the market

Approach #2: Equal-Weight Allocation (Balanced)

Strategy: Equal weight to each sector (9% each for 11 sectors) Allocation:
  • 9% Technology
  • 9% Financials
  • 9% Healthcare
  • 9% Consumer Discretionary
  • 9% Communication Services
  • 9% Industrials
  • 9% Consumer Staples
  • 9% Energy
  • 9% Utilities
  • 9% Real Estate
  • 9% Materials
(Total: 99%, leave 1% cash for flexibility) Pros:
  • True diversification (no over-concentration)
  • Less dependent on tech sector performance
  • Automatically “buys low, sells high” when rebalancing
  • Historically outperforms market-weight by ~1-2% annually
Cons:
  • Requires more frequent rebalancing
  • May underperform if tech continues dominating
  • More trades = potentially more taxes
Best for: Investors who want true sector balance

Approach #3: Custom Allocation (Advanced)

Strategy: Customize based on your goals, timeline, and economic outlook Example: Growth-Oriented (Age 30, 30-year horizon) Allocation:
  • 35% Technology (overweight for growth)
  • 15% Healthcare (growth + defensive)
  • 12% Consumer Discretionary (growth)
  • 10% Financials
  • 8% Communication Services
  • 8% Industrials
  • 5% Consumer Staples (underweight, less need for defense)
  • 3% Energy
  • 2% Materials
  • 1% Utilities (underweight, too slow for young investor)
  • 1% Real Estate
Rationale:
  • Heavy in growth sectors (tech, healthcare, consumer discretionary)
  • Light on defensive/low-growth sectors (utilities, staples)
  • Time horizon allows for higher risk

Example: Balanced (Age 45, 20-year horizon) Allocation:
  • 22% Technology (slightly below market-weight)
  • 15% Healthcare
  • 12% Financials
  • 10% Consumer Staples (increased defense)
  • 10% Consumer Discretionary
  • 8% Industrials
  • 7% Communication Services
  • 5% Energy
  • 5% Utilities (increased defense)
  • 3% Real Estate
  • 3% Materials
Rationale:
  • Balanced between growth and defense
  • Modest tilt toward stability (staples, utilities up)
  • Reduced tech concentration (risk management)

Example: Conservative/Income (Age 60, 10-year horizon) Allocation:
  • 15% Technology (reduced, too volatile)
  • 18% Healthcare (defensive growth)
  • 15% Consumer Staples (defense + dividends)
  • 12% Utilities (high dividends, stability)
  • 10% Financials (dividend income)
  • 10% Real Estate (REIT income)
  • 8% Industrials
  • 5% Communication Services
  • 4% Consumer Discretionary (reduced exposure)
  • 2% Energy
  • 1% Materials
Rationale:
  • Heavy in defensive sectors (staples, utilities, healthcare)
  • Dividend-focused sectors (REITs, utilities, staples)
  • Reduced volatility (less tech, less discretionary)
  • Still some growth (healthcare, industrials)

  • Full control over individual holdings
  • Can select quality companies you believe in
  • Potentially outperform sector ETFs with good stock picking
Cons:
  • More research required (22 stocks to analyze)
  • Higher single-stock risk
  • More time to manage and rebalance

Method #3: Hybrid (Core ETFs + Satellite Stocks)

Combine sector ETFs for most allocation, individual stocks for favorites Example: $10,000 portfolio Core (70% = $7,000 in Sector ETFs):
  • $1,400 VGT (Technology) - 14%
  • $1,050 VHT (Healthcare) - 10.5%

  • $600 MSFT (Tech conviction pick)
  • $600 JNJ (Healthcare conviction pick)
  • $600 V (Financials conviction pick)
  • $600 AMZN (Consumer Discretionary conviction pick)
Pros:
  • Best of both worlds (diversification + customization)
  • Reduced research burden (only analyze 5 stocks)
  • Can express high-conviction ideas with satellite
Cons:
  • Potential overlap (VGT holds MSFT and NVDA too)
  • More complex to rebalance
  • Still requires some stock picking skill

Rebalancing Your Sector Allocation

When to Rebalance

Option 1: Calendar Rebalancing
  • Rebalance every 6-12 months on a set date
  • Simple, no monitoring required
  • Example: Every January 1st
Option 2: Threshold Rebalancing
  • Rebalance when any sector drifts >5% from target
  • More responsive to market changes
  • Example: Technology target is 25%, rebalance if it hits 30% or 20%
Option 3: Hybrid
  • Check quarterly, rebalance if any sector is >5% off target
  • Balance between calendar and threshold approaches
Ask Sage:
Hey Sage, should I rebalance my sector allocation?

Current allocation:
- Technology: [%]
- Healthcare: [%]
- [list all 11 sectors with current %]

Target allocation:
- Technology: [%]
- Healthcare: [%]
- [list all 11 sectors with target %]

Which sectors are significantly off target? What trades should I make to rebalance?

How to Rebalance

Method 1: Sell Overweight, Buy Underweight Example:
  • Technology drifted from 25% target to 35% (overweight by 10%)
  • Energy drifted from 5% target to 3% (underweight by 2%)
Action:
  • Sell 10% of tech holdings
  • Buy energy with proceeds
  • Results in closer to target allocation
Pros: Mechanically rebalances to target Cons: Triggers capital gains taxes (in taxable accounts)
Method 2: Direct New Contributions to Underweight Sectors Example:
  • Technology: 35% (overweight)
  • Energy: 3% (underweight)
  • Adding $1,000 new money
Action:
  • Put $500 in energy (brings it closer to 5% target)
  • Put $300 in other underweight sectors
  • Put $200 in balanced sectors
  • Don’t add any to technology
Pros: No selling (no taxes), still rebalances over time Cons: Slower to rebalance Best for: Taxable accounts where you want to avoid capital gains
Method 3: Harvest Tax Losses + Rebalance Example:
  • Technology up 50% (overweight, would trigger big tax bill if sold)
  • Energy down 20% (underweight, can sell at a loss)
Action:
  • Sell energy position at a loss (creates tax loss to harvest)
  • Immediately buy it back in correct proportion
  • Use tax loss to offset gains from trimming tech
  • Sell some tech (offset by energy loss)
  • Rebalance to targets
Pros: Rebalance while minimizing tax impact Cons: Requires careful planning, watch out for wash sales

Using Money Monty to Analyze Sectors

Sector Health Check

Prompt:
Hey Money Monty, can you give me a health check on the [SECTOR] sector?

Analyze:
1. Recent performance (YTD, 1-year, 3-year returns)
2. Earnings growth trends for sector
3. Valuation (P/E ratio vs. historical average)
4. Major tailwinds and headwinds
5. Top-performing stocks in the sector
6. Underperforming stocks in the sector
7. Overall outlook: Bullish, neutral, or bearish?

I want to understand if I should be overweight, neutral, or underweight this sector.

Sector Comparison

Prompt:
Hey Money Monty, I'm trying to decide between increasing my allocation to [SECTOR A] or [SECTOR B].

Can you compare:
1. Recent performance trends
2. Valuation (which is cheaper?)
3. Growth outlook (which has better earnings prospects?)
4. Risk factors for each
5. Which is better positioned for the current economic environment?

Help me decide where to allocate new capital.

Finding Best Stocks in a Sector

Prompt:
Hey Money Monty, I want to add exposure to the [SECTOR] sector.

Can you suggest the top 5 stocks in this sector based on:
1. Strong fundamentals (earnings growth, margins, ROE)
2. Reasonable valuation (not wildly expensive)
3. Competitive positioning (market leaders)
4. Analyst sentiment

I want to buy 1-2 of the best stocks in this sector.

Common Sector Allocation Mistakes

Mistake #1: Unintentional Concentration

The Trap: You think you’re diversified, but you’re actually concentrated. Example:
  • Own SPY (28% tech)
  • Also own individual tech stocks (AAPL, MSFT, NVDA)
  • Also own QQQ (tech-heavy)
  • Actual tech allocation: 40-50% of portfolio!
The Fix:
  • Calculate your TRUE sector exposure (including all holdings)
  • If you own S&P 500 fund, account for its sector weights
  • Adjust individual holdings to compensate
Ask Sage:
Hey Sage, calculate my true sector allocation:

I own:
- 50% SPY (S&P 500)
- 15% QQQ (Nasdaq-100)
- 10% MSFT
- 10% AAPL
- 10% JNJ
- 5% XOM

What's my ACTUAL sector allocation across all holdings? Am I over-concentrated in any sector?

Mistake #2: Chasing Last Year’s Winner

The Trap:
  • 2023: Tech sector up 50%
  • 2024: You go all-in on tech
  • 2024: Tech underperforms, other sectors lead
Example:
  • Energy was best sector in 2022 (+60%)
  • Everyone loaded up on energy in 2023
  • Energy was worst sector in 2023 (-10%)
The Fix:
  • Don’t chase performance
  • Rebalance AWAY from outperformers (sell high)
  • Rebalance INTO underperformers (buy low)
  • This forces you to buy low, sell high

Mistake #3: Ignoring Valuations

The Trap: Staying overweight in expensive sectors just because “they always go up” Example (2021):
  • Tech sector P/E: 35× (vs. historical 22×)
  • Energy sector P/E: 10× (vs. historical 15×)
  • Investors: “Tech is the future, who cares about valuation!”
  • 2022: Tech -30%, Energy +60%
The Fix:
  • Compare sector P/E ratios to historical averages
  • Overweight sectors trading below historical P/E
  • Underweight sectors trading above historical P/E
Ask Money Monty:
Hey Money Monty, which sectors are cheap or expensive right now based on historical P/E ratios?

For each sector:
1. Current P/E ratio
2. 10-year historical average P/E
3. Is it expensive, fairly valued, or cheap?

Help me identify which sectors are good values.

Mistake #4: Market Timing Based on Predictions

The Trap: “I think a recession is coming, so I’m going 100% consumer staples and utilities.” What usually happens:
  • Recession doesn’t come for 2 years
  • You miss growth in tech, discretionary
  • When recession finally comes, it’s already priced in
The Fix:
  • Don’t go to extremes (0% or 100% of a sector)
  • Use tactical tilts (reduce tech from 28% to 20%, not to 0%)
  • Stay diversified even when making calls
  • Recognize you might be wrong
